We might EXPECT that the rate of expansion might be slowing due to gravity, but the fact is that we don't have any idea. Is there such a thing as "dark energy", and if so, does it act repulsively? We don't have a clue.
But hold that thought; we may find out in the next 50 years or so.
What else can I help you with?
What is an accelerating universe?
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
Recent results from very bright supernovae in very distant galaxies seem to indicate that the expansion of the universe?
Recent observations of very bright supernovae in distant galaxies suggest that the expansion of the universe is accelerating. This acceleration is attributed to a mysterious force known as dark energy, which constitutes about 68% of the universe. The findings challenge previous notions of a decelerating universe and indicate that the rate of expansion is increasing over time. These results have significant implications for our understanding of cosmology and the ultimate fate of the universe.
Dark energy seems to be accelerating the expansion of the universe causing what?
That means that the Universe expands faster and faster. It causes the Universe to grow, and the general density of matter in the Universe to decrease over time.
How was the cosmoligical constant proved wrong by Hubble?
Hubble's discovery of the expanding universe in the 1920s provided evidence against the static universe model favored at the time, which relied on a cosmological constant to maintain stability. By observing that galaxies were moving away from each other and the universe was expanding, Hubble's findings contradicted the need for a cosmological constant to explain a static cosmos.
Humble space telescope's contributions to space?
The Hubble Space Telescope has made numerous contributions to space science, including: discovering that the expansion of the universe is accelerating due to dark energy, capturing detailed images of distant galaxies and nebulae, providing valuable data on exoplanets and their atmospheres, and helping to refine the measurement of the Hubble constant, which determines the rate of the universe's expansion.
Does a coasting universe expand forever?
If a universe is coasting, it means it is expanding at a constant rate and will continue to do so forever without accelerating or decelerating. This expansion will result in the universe becoming increasingly larger over time.
The amount of energy in the universe is?
The Total amount of energy in the universe is E=mc2 =1.9 E70 Joules.
What is an accelerating universe?
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
What is accelerating universe?
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
Where in the universe is there no force?
As a layman my thought is that there is no place anywhere in the universe that is free from force. Even in the remotest reaches of inter-galactic space, an unimpeded object would be experiencing many forces. It's just that the forces would be balanced. The object would not be accelerating and it would not be decelerating.
If the hubble constant H is larger at great distances then what is happening?
An increasing Hubble constant at great distances indicates an accelerated expansion of the universe. This phenomenon is attributed to dark energy, a mysterious force causing the universe to expand at an increasing rate. It suggests that as the universe expands, the distance between galaxies grows larger, leading to a greater Hubble constant at greater distances.

Which model of the universe requires the concept of the dark energy?
The one where the universe is expanding and accelerating.
What is a component of the universe that seems to be counteracting the effect of gravity and accelerating the expansion of the universe?
Dark energy.
How does the age of the universe relate to the hubble constant?
The age of the universe is inversely proportional to the Hubble constant. A smaller Hubble constant would imply a younger universe, while a larger Hubble constant would suggest an older universe. This relationship is based on the assumption that the expansion rate of the universe has been constant over time.
Will space time be flat if the universe continues to expand at an accelerating rate?
As the universe continues to expand at an accelerating rate, space-time is expected to remain flat according to current scientific theories.
What are the twenty constants of the Universe?
Some constants of the Universe include the speed of light, gravitational constant, Planck's constant, and the fine structure constant. These constants govern the fundamental forces and properties of the Universe and are crucial in understanding how the Universe functions.
